0 in physics, a wave moving in the same direction as the vibrations (= fast movements backwards and forwards) of the particles of the substance through which it is moving -- fala podłużna
The amplitude of the transverse wave finally increases to about 2.7 times that of the longitudinal wave.
The length-to-width ratio 1 is assumed t o be far from integral multiples of so that the longitudinal wave is not resonantly excited.
For such conditions, the amplitude of the longitudinal wave is of higher order than that of the resonant cross-wave.
The second inequality refers to the stability of the stationary longitudinal wave subject to transverse perturbations.
Production of high-quality electron beams in numerical experiments of laser wakefield acceleration with longitudinal wave breaking.
On the stable branch, starting from the turning point, the amplitude of the longitudinal wave decreases while the amplitude of the transverse wave increases and dominates the three-dimensional wave motion.
The rarefaction is the farthest distance apart in the longitudinal wave and the compression is the closest distance together.
One compression and one rarefaction make up one longitudinal wave.
